Signal transmission fuse

Abstract

A signal transmission fuse is made of a tube (36) which encases a support tape (14) having a reactive coating (18′) which is adhered to one side of the tape by a binder. A method of making the signal transmission fuse includes depositing on the support tape (14) a reactive paint (18) including a binder, which paint dries to form a reactive coating (18′). The coated support tape (14′) is then folded, i.e., formed into a channel configuration, to provide an inner concave side of the tape on which the reactive coating (18′) has been disposed. The coated support tape is then enclosed, e.g., within an extruded plastic tube (36). One side of the support tape may be made of a first material (14a) to which the reactive coating adheres, and a second side may be made of a second material (14b) which bonds or adheres to the inner surface (36a) of the plastic tube (36) enclosing the coated support tape (14′). The binder causes even high loadings of the reactive coating (18′) to adhere to the coated support tape (14′) to prevent reactive material migration. The support tape also shields the reactive material from the hot, freshly extruded surrounding plastic tube (36) during manufacture.
